Abstract
The viscosity of liquid organic systems is increased by adding thereto an organophilic clay gellant which is the reaction product of a smectite-type clay having a cation exchange capacity of at least 75 milliequivalents per 100 grams of said clay and from 100 to 120 milliequivalents per 100 grams of clay of methyl or benzyl trialkyl ammonium salt, wherein the alkyl groups independently contain from 14 to 20 carbon atoms.
Claims6
An organophilic clay gellant having enhanced dispersibility in organic systems and capable of increasing the viscosity of a liquid organic system without the addition of a polar organic dispersant, comprising the reaction product of a methyl or benzyl trialkyl ammonium compound, wherein the alkyl group contains 14 to 20 carbon atoms, and a bentonite clay having a cation exchange capacity of at least 75 milliequivalents per 100 grams of said clay, and wherein the amount of said ammonium compound is from 100 to 120 milliequivalents per 100 grams of said clay, 100% active clay basis.
An organophilic clay gellant having enhanced dispersibility in organic systems comprising the reaction product of an ammonium compound having the formula:
- ##STR2## wherein R.sub.1 is CH.sub.3 or C.sub.6 H.sub.5 CH.sub.2 ;
- R.sub.2, R.sub.3 and R.sub.4 are alkyl groups containing 14 to 20 carbon atoms, and mixtures thereof, based on 100% and where M.sup.- is selected from the group consisting of Cl.sup.-, Br.sup.-, NO.sub.2.sup.-, OH.sup.-, and C.sub.2 H.sub.3 O.sub.2.sup.-, and sodium bentonite, and wherein the amount of said ammonium compound is from 100 to 120 milliequivalents per 100 grams of said clay, 100% active clay basis.
